Duplex Steel Pipe Fittings are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, along with trace amounts of nitrogen, carbon, and manganese. This special mix creates a balanced microstructure that features both ferritic and austenitic phases, resulting in impressive tensile strength, high yield strength, and outstanding resistance to corrosion and stress cracking. Typically, the tensile strength falls between 620–880 MPa, with a yield strength of 450–620 MPa and an elongation of 25–35%. These fittings are known for their excellent toughness, high fatigue resistance, and stability even in elevated temperatures and harsh chemical environments.
